SASH cons'rnnc'rron.

To all whom it may concern:

Be it known that I, EDMUND M. ERB, residing'at Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Sash Construction, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it apconstruct a hollow metallic sash in such man;

ner that the same will not tend to become sprung or distorted when raised within the frame.

' Another object thereof is to provide a se-.

cure suppo'rtupon the sash frame for the devices employed for releasing the sash from the window frame during theraising or lowering of the sash.

Other objects will be in part obvious and in part pointed-out hereinafter.

The invention accordingly consists in the features ofconstruction, combinations of elements and arrangement ofparts which will be exemplified in the construction herein ametallic sash having my invention applied .ing.

after set forth, and the scope of the a plication of which will be indicated in the following claims.

- In the accompanying drawing, wherein one of several various possible embodiments of my invention '18 shown, Figure 1 1s a vlew in elevat on of a portion of the bottom ra l of thereto. F ig. 2 is a cross sectional view taken substantially on line (kl-a, Fig; 1.

Similar reference characters refer to similar parts-throughout both views of the draw- Referring now to the drawing, 1 indicates form.

Inasmuchas considerable strain is imposed upon the bottom rails of sashes when a lifting stress isplacedthereon, as when they are ralsed in the, frame, it is desirable that the devices mounted thereon f employed for releasing the locking devices and lifting the Specification of Letters Patent. Application filed January 10. 1907- Serial No. 351.650.

Patented. Nov. 19,1907.

I sashes be supported in such manner that the sashes will retain theirshape during the raisin and lowering thereof. Inthe resent instance, :a lifting plate 2 is mounte u on bottom sash rail, sald plate being provi( ed with a finger or hand-hold shelf as at 3, and upon plate 2. in the present instance, are pivotally mounted fin er levers 4. The shafts 6,upon which these ger levers are mounted extend within. the interior of the sash and are connected with levers or similar, devices, catches, wedges or other sash releasing means, not

tial part of my invention.

. In order to stiffen the sash. and to provide a firm support for plate 2, there is driven into the interlor'of the sash a hollow reinforcing conforms to the interior shape of bottom rail interior walls ofbottom rail are in tight engagement. Clamp screws, such as shown at the exterior Wall of bottom rail an lnto the v reinforcing member.

It will accordingly be seen that I have provided aconstruction well adapted to attain the ends and objects of my invention. The lifting plate being supported .by means located inteilorly of the hollow rail is given a firm and rigid support and lifting stresses will accordingly be distributed throughout the entire section of the bottom rail engaged by the reinforcing member. This will not only prevent'the clamp screws from working loose or'from strippin the threading in the wall of the rail, but will at all times insure that the liftling plate be immovably attached to the ra:

ber located in the bottom rail of the sash, it

any desired portion of the sash frame;

Certain features directed to the specific structure of the sash rail shown hereinare described and claimed -in my application Serial No. 351,650, filed of even date herewith.

above construction and many a parently 'widely different embodiments of t 1s inven-' tion could be made without de arting from the scope thereof, it is intended t at all matter contained in the above description or shown in the accompanying drawings shall be in- EDMUND- M. ERB, or JERSEY CITY, NEW JERSEY, AssicNoR TO ROBERT M. DIXON, or EAST herein shown as the same comprise no essensection 7, the exterior of which substantially 1. The exterior walls'of member 7 and the 8, are passed throu h plate 2 and tappedinto i While 'I have shown the reinforcing mem- I is obvious that the same may be provided at] As many changes could be made in the terpreted as illustrative and not in a limiting sense. 7

A metallic sash frame the bottomrail v of which is comprised by a hollow metallic member having a hollow'reinforeing member seated therein and in tight engagement with the inner walls thereof, va lifting plate carrying sash releasing, devices located exteriorly of said rail, and clamp screws extending through said plate andthreaded into said rail and into said'reinforcing member.

3. A sash frame having a bottom rail comprised by a hollowmetallic member having driven therein ahollow reinforcing member the exterior walls of which are in close fitting engagement with the interior walls of said v first-mentioned member, a lifting plate carrying sash releasing devices locatedexteand tapped into said members.
